'EastEnders' Cora reveals her biggest secret - preview

Cora Cross has a huge confession to make as she opens up about her past on EastEnders next week.

The charity shop worker sparks concern among her loved ones as she starts behaving strangely in the coming days, and Patrick Trueman is her choice of confidante when she is unable to keep the truth to herself for any longer.

Patrick is intrigued when Cora (Ann Mitchell) appears to be in a downbeat mood on November 12, but the pieces of the puzzle start to fall together when she bakes a cake to mark the birthday of her first-born daughter Ava.

Cora informs Patrick that Ava didn't die at all - she put the newborn up for adoption as that was the way it had to be. Patrick is shellshocked to realise that Cora has another daughter out there, now known as Ava Hartman.

In the days that follow, Cora regrets being so candid with Patrick and shuts down any further discussion on the matter - but Tanya is worried over her mother's welfare as it's clear that she still has something on her mind.
